Finger Sizing and Ring Size Chart
Clothes and shoes are measured differently for men and women. However, men's and women's ring size is measured the same. Ring size is measured on a ring mandrel by the inner diameter of the band. When measured, a men's ring size nine measures the same as a women's ring size nine.
Important note: Ring bands will vary on the width. A wider band may require a larger size ring. The inner diameter might be the same, but a wider band will feel tight due to the amount of metal in contact with your finger.
If you wear a size 7 in a thin 1.5mm wide band, a size 7 in an 8mm wide band may feel tight even knowing both are a size 7. We recommend a larger half or full ring size if you shift from a thin band to a more wide band.
We have an easy exchange process if you order the wrong inner diameter. If you do not know your ring size, we have a quick finger sizing tool here.
